sections:
Please continue to read "switch Installation" after reading this section.
Safety notice
Ensure safety as the following principals
Keep the chassis areas clean and dust-free during and after installation
；
Put the cover in a safe place;
Put the tools away from walk areas where you and others could fall over them
；
Do not wear loose clothing that could get caught in the chassis. Fasten your tie or
scarf and roll up your sleeves.
If the working environment could cause damage to your eyes, wear protection
glasses;
Do not do anything that causes damage to human or device.
Safety warnings
Please follow the instructions below. Any mal-operation could cause damage to human;
Read the installing instruction carefully before operating the system;
Only qualified mechanics are allowed to install or replace the switch;
Before working on a chassis or working near power supplies, unplug the power
cord on AC units; disconnect the power at the circuit breaker on DC units.
Unplug AC plug and disconnect DC connection before working on the case or
near the power supply.
Ultimate configuration of this product must follow all applicable national laws
and regulations.
Safety principal of operation with electricity
Follow these guidelines when working on equipment powered by electricity.
Before working on equipment that is connecting to power lines , remove jewelry
(including rings, necklaces, and watches). Metal objects will heat up when
connect to the power and ground and can cause serious burns or can weld the
metal objects to the terminals.
Before working on a chassis or working near power suppliees, unplug the power
cord on AC units, disconnect the power at the circuit breaker on DC units.
Do not touch the power supply when the power cord is connected .
Incorrect connection of this or connected equipment to a general purpose outlet
could result in a hazardous situation.

Read the installation instructions carefully before you connect the system to its
power source.
Notes
：
Look carefully for possible hazards in your working area, such as moist floors,ungrounded
power extension cable, frayed power cord.
Locate the emergency power off switch for the room in which you are working. Then, if an
electrical accident occurs, you can act quickly to turn off the power.
Power off the switch and unplug the power cord before doing the following:
Installing or removing the chassis
Working near power supply
Do not work alone if potentially hazardous condition exists.
Never assume that power is disconnected from a circuit. Always check.
If an accident occurs ,proceed as follows:
Turn OFF power to the system
Use caution
Determine if the victim needs rescue breathing or external cardiac compression; then take
appropriate action.
If possible, send another person to get medical aids. Otherwise, assess the condition of the
victim and then call for help.
Preventing electrostatic discharge damage
Electrostatic discharge can damage equipment and impair electrical circuitry. It occurs
when electronic components are improperly handled and can result in complete or
intermittent failures.
Always follow electrostatic discharge prevention procedures when removing and
replacing components. Ensure that the chassis is electrically connected to earth ground.
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect
the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD
voltages to ground.To properly guard against ESD damage and shocks,the wrist strap
and cord must be used effectively.If no wrist strap is available, ground yourself by
touching the metal part of the chassis.
General site requirements
This section describes the requirements your site must meet for safe installation and
operation of your system. Ensure that your site is properly prepared before beginning
installation.
Site environment
The switch can be placed on a desktop or mounted in a rack.The location of the chassis
and the layout of your equipment rack or wiring room are extremely important for proper
system operation. Placing equipment too close together, inadequate ventilation, and
inaccessible panels can make system maintenance or cause system malfunctions and
shutdown.

When planning your site layout and equipment locations, remember the precautions
described in the next section, "Preventive Site Configuration". If you are experiencing
shutdowns or unusually high errors with your existing equipment, this precautions might
help you isolate the cause of failures and prevent future problems.
Preventive site configuration
The following precautions will help you plan an acceptable operating environment for
you switch and help you avoid environmentally-caused equipment failures:
Ensure that the room in which you operate your system has adequate air
circulation .Electrical equipment generates heat. Ambient air temperature might
not be able to cool equipment to acceptable operating temperatures without
adequate circulation.
Always follow the EDS-prevention procedures to avoid damage to equipment.
Damage from static discharge can cause immediate or intermittent equipment
failure.
The chassis is designed to allow cooling air to flow effectively inside it. An open
chassis allows air leaks, which might interrupt and redirect the flow of cooling air
from internal components.
Configuring Equipment rack
The following information will help you plan an acceptable equipment rack
configuration.
The equipment in the rack will heat when working. So enclosed racks must have
adequate ventilation.The equipment should not be put too close to each other to
ensure the racks are not overheat.
When mounting a chassis in an open rack ensure that the rack frame does not
lock the intake or or the exhaust ports. So check the position of the chassis when
it is seated all the way into the rack.
Ensure that you provide adequate ventilation for equipment at the bottom of rack.
Baffles can help to isolate exhaust air from intake air, which also helps to draw
cooling air through the chassis. The best placement of the chassis on the airflow
in the rack, which and be found by experimenting with different arrangement.
Power supply condition
Check the power at you site to ensure that you are receiving "clean" power. Install a
power conditioner if necessary. Ensure that a fuse or circuit breaker no larger than
240V,10A in terminal is used on the phase conductors.
Warning
：
If the power system does not connect to the earth properly , the variables of input power is big or exist
excess pulse, it will add error ratio of communication equipment , even to damage the hardware system.
